Spatial dependence of the superexchange interactions for transition-metal trimers in graphene
Charles B. Crook, Gregory Houchins, Jian-Xin Zhu +3
This study examines the magnetic interactions between spatially-variable manganese and chromium trimers substituted into a graphene superlattice. Using density functional theory, w…
Computational investigation of the electronic and optical properties of planar Ga-doped Graphene
Nicole Creange, Costel Constantin, Jian-Xin Zhu +2
We simulate the optical and electrical responses in gallium-doped graphene. Using density functional theory with a local density approximation, we simlutate the electronic band str…
Proximity-induced magnetism in transition-metal substituted graphene
Charles B. Crook, Costel Constantin, Towfiq Ahmed +3
We investigate the interactions between two identical magnetic impurities substituted into a graphene superlattice. Using a first-principles approach, we calculate the electronic a…
ScGaN Alloy Growth by Molecular Beam Epitaxy: Evidence for a Metastable Layered Hexagonal Phase
Costel Constantin, Hamad Al-Brithen, Muhammad B. Haider +2
Alloy formation in ScGaN is explored using rf molecular beam epitaxy over the Sc fraction range x = 0-100%. Optical and structural analysis show separate regimes of growth, namely…
